CRPC has been able to build up an infrastructure and body of personnel that can assure the viability of its operations and serve claimants in the most effective and timely way. The CRPC regional offices in particular provide a model of capacity building. Staffed entirely by local personnel, the regional offices are run by a Head of Office supported by a Legal Advisor, with operations supervised by the Executive Office management in Sarajevo. There is ongoing legal training for on-site lawyers, technical training for the data entry clerks working with CRPC's claims software system, and promotion of management skills in the senior office staff. Further, the regional office network facilitates and demands co-operation between ethnicities: the staff for regional offices, who represent a cross-section of each ethnic group in BiH, meet monthly to discuss issues of procedure and administration, including burden-sharing between locations and co-operative solutions for common problems. In this sense, the CRPC is building a sustainable structure for efficient and equitable property claims collection that also ensures collaboration between ethnic groups and cultivation of professional and technical skills. CRPC has approximately 320 staff working in the Executive Office in Sarajevo and in a network of regional offices. In BiH CRPC has offices in Sarajevo, Mostar, Brcko, Banja Luka, Tuzla, and Bihac. In Yugoslavia CRPC works out of Belgrade, Novi Sad and Pozega. In Croatia, claims can be filed in Zagreb and Slavonski Brod. CRPC staff also work in mobile outreach teams to reach more isolated areas.
